Unit 3: Chapter 6 - Energy And Metabolism Flashcards
(21 cards)
What is the cymbal for Glucose?
C6 H12 O6
What is the cymbal for Oxygen?
O2
What is the symbol for carbon dioxide?
CO2
What is the cymbal for water?
H2O
Name the symbolic formula for cellular respiration.
C6H12O6 + 6O2 —> 6CO2 + 6H2O + energy
Name the formula of cellular respiration in words.
Sugars + Oxygen —> Carbon dioxide + Water
What is cellular respiration also known as?
A catabolic pathway.
What is a catabolic pathway?
A sequence that breaks down complex molecules into smaller units, usually releasing energy in the process.
Name the symbolic formula of Photosynthesis.
6CO2 + 6H2O + Energy —> C6H12O6 + 6O2
Name the formula of photosynthesis in words.
Carbon dioxide + water —> sugars + oxygen
What is photosynthesis also known as?
An anabolic Pathway.
What is an Anabolic Pathway?
Those that require energy to synthesize larger molecules.
What is bioenergetics?
The concept of energy flow through living systems.
What do living things consume as a major source of energy?
Sugar!
What do consumed carbohydrates have?
Origins in photosynthesizing organisms like plants.
What happens during photosynthesis?
Plants use the energy from the sun to convert carbon dioxide gas into sugar molecules, like glucose.
What form is energy provided in during photosynthesis?
Adenosine triphosphate (ATP)
What is ATP?
A nucleic acid that provides energy to drive and support many processes in living cells.
What 4 cells do we see ATP as the energy source?
Muscle contractions, nerve impulse propagation, condensate dissolution, and chemical synthesis.
List 3 examples of anabolic (building) pathways
- Synthesizing sugars from CO2.
- Proteins from amino acid building blocks.
- Synthesis on new DNA strands from nucleic acids.
List 2 examples of Catabolic (breakdown) pathways.
- Breakdown of Glucose into ATP.
- Breakdown of fats.
